If they're going to do that, they'll need to dump the money for time bonuses into the placing prizes. Maybe make the place money deeper too.
even better: primes.
have a cash prize at pre-determined spots. Maybe at 5k have a thousand bucks up for the first to cross the line. Then at 15k, then at 30k, and then maybe a huge one at 40k, like 5 to 10 grand.
Can you imagine 3-4 guys (or more) attacking each other like crazy to hit 40k first?
Be pretty exciting to watch.
